THE BROWN COTTOX-BUG. 
(Euschistus servus Say.) 
DISTRIBUTION'. 
Dr. P. R. Uhler states a that Euschistus servus (PI. I, fig. 2: text 
figs. 12, 13) inhabits Texas, New Mexico, California, "Dakota/' 
Illinois, Maryland, and the Southern States generally. Mr. E. P. 
Van Duzee, who possesses the most extensive collection of the Penta- 
tomidaeof America, states 6 that he has not seen types of this species 
from north of New Jersey and Ohio or west of Kansas, Texas, and 
eastern New Mexico. In Texas the species is of common occurrence 
throughout the eastern half 
of the State, being much 
more common in the north- 
ern portion of this section 
than in the southern por- 
tion. Toward the western 
and northwestern portions 
of the State the species grad- 
ually diminishes in num- 
bers, possibly owing partly to 
decrease in cotton acreage. 
In Louisiana the brown cot- 
ton-bug is found throughout 
the State, though appar- 
ently, as in Texas, is more 
common in the central and 
northern than in the south- 
ern portion. 
FOOD PLANTS. 
The brown cotton-bug has *». '■'• 
been taken on several other 
plants in addition to cotton, but specific records of actual feeding have 
ii"' been made except in the case of specimens found feeding on the fruit 
of the orange in Florida/ and a specimen which the writer has observed 
feeding on green fruit and twigs of peach in confinement. The agents 
oi the Bureau of Entomology who were connected with the cotton 
boll weevil investigations have collected this species in Texas and 
Louisiana on the following plants: Helianthus (three localities . 
corn (two Localities), Heterotheca subaxiOaris two localities), Rud-
